Hi Raj,

If we bind the imageurl on click of the image it unnecessarily goes for a postback, so it is better to bind the url at the first go only and keep in hidden mode.

Actually no need of having the asp:Image control simple img tag can also solve this problem.

The below code will show an image in popup on click of the button. Please change this ti suit your requirement.

HTML

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript" src="jquery-1.8.2.min.js"></script>
    <script type="text/javascript" src="jquery-ui-1.8.24.min.js"></script>
    <script type="text/javascript">

        $(document).ready(function () {
            $("#MyImage").dialog({
                autoOpen: false
            });
            $('#ClickMe').on('click', function () {
                $('#MyImage').dialog("open");
            });
        });
    </script>
</head>
<body>
    
        <button id="ClickMe">Click to view Image</button>
         <asp:image id="MyImage" runat="server" style="display: none" imageurl="~/276609a.jpg" xmlns:asp="#unknown" />
    
</body>
</html>

I used ThickBox It is quite good and easy to implement.
Just add js and css file to page.

XML

<script src="Script/ThickBox.js" type="text/javascript"></script>
<link href="Css/ThickBox.css" rel="stylesheet" type="text/css" />

Small image inside image tag and full image inside <a> tag.
Remember to define <a> class name as "thickbox" only.

ASP.NET

<a class="thickbox" id="Image6" runat="server"><asp:image id="Image1" height="100" width="100" style="cursor: pointer" runat="server" xmlns:asp="#unknown" /></a>

C#

Image1.ImageUrl = "~/Image/" + Convert.ToString(reader["imagepath1"]);
Image6.HRef = "~/Image/" + Convert.ToString(reader["imagepath1"]);
